SiSiB® PC1118

Bis[(3-trimethoxysilyl)propyl]amine
Synonym: 3-(Trimethoxysilyl)-N-(3-(trimethoxysilyl)propyl)-1-propanamine

Countertype of Dynasylan 1124, Silquest A-1170

Chemical Structure


Introduction

SiSiB® PC1118 is a secondary aminofunctional silane possessing two symmetric silicon atoms. SiSiB® PC1118 may act as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers) or as a surface modifier.

SiSiB® PC1118 is a slightly yellowish liquid with an amine-like odor. It is soluble in alcohols, aliphatic or aromatic hydrocarbons.

Applications

SiSiB® PC1118 can be used in many applications, like:

- Foundry resins: as additive to phenolic,furan and melamine resins;
- Mineral-filled composites: for pre-treatment of fillers and pigments;
- Metal primers;
- Mineral fiber insulating materials, abrasives: as additive to phenolic resin binders;
- Sealants and adhesives: as primer or additive;
- Paints and coatings: as additive and primer for improving adhesion to the substrate.

SiSiB® PC1118 can be used to improve:

Product properties, such as
- Durability at high temperature and humidity;
- Flexural strength, tensile strength, impact strength and modulus of elasticity;
- Moisture and corrosion resistance ;
Processing properties, such as
- Excellent primerless adhesion;
- Higher filler loading;
- Homogeneous distribution of inorganic fillers in polymer matrices;
- Rheological behaviour: reduction in viscosity, newtonian behavior;
- Wet-out.
